Abstract
Lucky bamboo (Dracaena sanderiana hort. ex Mast. = Dracaena braunii) is a domestic species widely cultivated for ornamental purposes in China. In March 2022, a severe occurrence of anthracnose disease was observed on the stems of lucky bamboo plants in a greenery retail store located in Nanjing, Jiangsu Province, China. The morphological characteristics of isolates obtained from diseased stem tissues were identical with those described for Colletotrichum species. Based on multilocus phylogenetic analysis with the internal transcribed spacer (ITS), actin (ACT) gene, and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) gene, the pathogen was identified as Colleto-trichum gloeosporioides (Penz.) Penz. & Sacc. Pathogenicity was verified by mycelial plug-inoculating stem cuttings of one-year-old lucky bamboo plants and spray-inoculating whole one-year-old lucky bamboo plants, respectively. Koch’s postulates were fulfilled by the re-isolation of C. gloeosporioides from symptomatic tissues. To the best of our knowledge, this report describes the first time that C. gloeosporioides was observed to cause anthracnose on lucky bamboo in China.
